Vedic science, Ayurveda, Homoeopathy, Naturopathy, Allopathy, all talk about eating less to stay healthy. Following are the ways to eat less:

• The brain gets a signal that you have eaten only after 20 minutes, therefore, chew every bite of food at least 15 times. It not only provides enough hormones for enzymes but also sends signals to the brain. Therefore, the time spent per meal should be 20 minutes.
• The taste buds are only on the tip and side of the tongue. If you gulp food, the brain will not get signals. Eating small pieces and chewing them properly also sends the signals through the taste buds.
• The fullness of the stomach also decides how much one can eat. The brain gets signal only when the stomach is 100% full. Therefore, one should not overeat and fill the stomach to its size. Also, if you eat less, over a period of time, the size of the stomach will shrink.
